Problems after updating to RetroPie 3.6: Advmame won't detect Xbox 360 controller, video output ratios can't be changed

Hi /r/RetroPie,

I finally updated to 3.6. I followed every step in the official guide in the exact order and used the binary update. It went just fine and there were no errors, but I've run into a few issues now that I'm up and running:

• Advmame no longer detects my wireless Xbox 360 controller. All of the other emulators work with my Xbox controller, but not Advmame. It worked prior to the update. I've tried to disable, then re-enable the Xbox 360 controller drivers via the Setup menu. Didn't work. I can connect a keyboard and access the control binds, but Advmame won't respond to my controller key presses at all. I tried ssing the newer version of Advmame via the ROM launch configuration menu (I think it's Advmame 1.4?) and also rebooted the Pi.
• All of my ROMS only play in the old 640 x 480 video output mode, and it won't respond to any of the changes that I've tried to make to the default output mode. Even when I set it to 1280 x 720, it only displays 640 x 480

I'm using: Raspberry Pi 2 Model B RetroPie 3.6

Any suggestions?
